Splintless microsurgical anastomosis of the ureter in the dog.

In an experimental study in dogs, four different techniques of microsurgical anastomosis using Vicryl 8-0, have been compared: 1. Interrupted submucosal sutures; 2. Continuous submucosal sutures; 3. Full thickness interrupted sutures; 4. Full thickness continuous sutures. Intravenous urography and electron microscopic studies three months post operatively showed that ureteric stricture had occurred in only 2 cases out of 24. Microsurgical techniques are recommended for ureteric anastomoses.
